Ecological surveys

To protect biodiversity it is essential to identify the areas with the highest ecological values. This includes areas with endangered species and habitats that are protected by law. Identifying rare or protected species is therefore vital for conservation and planning. In many cases, only experienced personnel are able to determine if an area has high ecological values. EnviroPlanning offers consultants with experience in finding and identifying threatened species as well as understanding their interactions with their habitat.

All Swedish bat species are protected by law. This means it is forbidden to trap, kill, move or disturb bats or their roost sites. These nocturnal animals are surveyed using special bat detectors. EnviroPlanning can assist whenever there is a need to study and/or survey the bat fauna, for example, wind farm projects, municipal planning or species surveys or monitoring programmes.

EnviroPlanning carries out studies of watercourses, where occurrence of different habitat types, e.g. spawning grounds, are recorded.

Birds can be sensitive to changes in the environment. Bird surveys can be carried out to assess which species of birds are present in an area, an whether any of these require special protection measures. EnviroPlanning provides bird survey services, for example in infrastructure projects.

Changes to the benthos (organisms that live on or in the river or lake bed) can indicate some form of environmental disturbance. EnviroPlanning can provide experienced personnel for studies of the benthos in different types of freshwaters.

The aquatic environment can be difficult to monitor because it is often not possible to directly observe whether a stream or a lake is affected by human activity. However, it can be important to investigate the wellbeing of fish in a stream or lake. Several fish species are of economic importance, and many species play an important role in the aquatic ecosystem because of their position high in the food chain. Two main methods are used to investigate how much, and which type of fish can be found beneath the surface: electrofishing and net fishing. Electrofishing is appropriate in running water, where fish within a particular stretch can be caught using an electrical field that stuns the fish. Net fishing is used in lakes and coastal waters to investigate fish numbers and species composition.
